All of the above + feathers.

I couldn't help but laugh when reading this as giraffes are the very first object I spot LOL.

Pins and needles are difficult for me.

Bats... because I never know if I should look for a flying mammal or a baseball bat. LOL

I have problems sometimes with butterflies... they often blend in so well you can't spot them.

Hammers!...It's a mental block..I hate hammers!

Feathers for me. In Mishap: An Accidental Haunting I could not find the fishing reel, had to use a hint every time I had to look for one.

For me it's bats and bats (too) and pencils. I've played one freebie here called find the numbers that I have trouble with also.

Different names for objects that are used from other countries, not the name that I would call the object. But I also love learning the names called, so it really is a plus! I think coloration, like pencils, are also difficult for me.

Feathers and mushrooms are always hard for me to find but matchsticks and needles are not a problem... go figure

Along w/many of the things already mentioned here,
I often have problems with funnels,
they are so easily 'morphed' in w/another item.
